- According to Euler's column theory, the crippling load of a column is given by [img=128x27]18032d66b024c7f.png[/img]. In this equation, the value of μ for a column with both ends hinged, is ( ) A: 0.25 B: 0.5 C: 1.0 D: 2.0
- If the coefficient of equivalent length of the long column is doubled, the critical pressure of the column will be ( ). A: Doubled B: Increased by 4 times C: One half of the original D: A quarter of the original
- Inject a little mercury (Hg) into a horizontal glass capillary tube. The two ends of the horizontal mercury column are convex. If heating the right convex of mercury, the mercury in the capillary will move ( ). A: to the left B: to the right C: to both ends D: no
- The slender column is under axial compressive load P, the critical load [img=23x22]1803a0faa055141.png[/img] is independent of ( ). A: the material of the column B: the length of the column C: the magnitude of the P D: the shape and dimension of the cross section of the column
- When a column is subjected to an eccentric load, the stress induced in the column will be ( ) A: direct stress only B: bending stress only C: shear stress only D: direct and bending stress both
